Lee Heon is the king of Joseon. Seven years ago, when he was crown prince, his beloved wife died. To this day, he has not been able to come to terms with her death. Over the past seven years, the royal family and members of the government have tried unsuccessfully to persuade King Lee Heon to remarry. The nation has also implemented a geumhonryung edict, which prohibits all unmarried women from marrying as long as the king remains unmarried. The people are furious about the marriage ban. One day, King Lee Heon hears about a woman named Ye So Rang, who claims that the spirit of the king’s late wife exists within the royal palace. Meanwhile, Ye So Rang is a con artist who claims to interpret the signs of martial harmony. She is arrested and imprisoned where Officer Lee Shin Won works. To get out of her predicament, she pretends to be possessed by a spirit in front of Lee Shin Won. During her ruse, she mentions that the spirit of King Lee Heon’s late wife exists within the royal palace. She is then brought before the king, who asks her if she can truly see the spirit of his late wife. To survive, Ye So Rang acts as if her body were possessed by the king’s late wife. Ye So Rang’s lies grow increasingly elaborate and daring.
